To all whom iiimay concern.-

Be it known that we, ALBERT Enwano DABBS ST NLEY Werrnr SAVAGE, and An FRED HAROLD HINDLE, sub ects of the King of Great Britain, residin at 19 Rowan a'venue, Whalley Range, anchester, in the county of Lancaster, England, 55. Brook road, 'Ghorlton cum Hardy, Manchester aforesaid, and 51 bandford road, Moseley, Birmin ham, inthe 'county'of Warwick, En lan respectively, have invented a new and useful Improvement in Roller or Ball Bearings; and we do hereby declare the following to be a full, clear, andexact description of the same.

This invention relates to roller or ball bearings of the kind in which balls or rollers are disposed between the shaft which the bearing supports 'or the housing and the surface of a ring freely carried by the housing or by members mounted on the shaft.

The object of thepresent invention is to provide an improved bearing whereby automatic self-adjustment of the bearing will be attained for inequalities in the shaft due either to the incorrect positioning of the bearing or to whirlingof the shaft due to long distances between the bearings.

According to this invention in roller or ball bearin s having a ring freely carried or supported liy the housing or by members mounted on the shaft, the said ring is formed as a close helix and a clearance is provided along the whole length of the helix between the helix and its support. This application is a divisional of application filed December 5. 1918, Serial No.

i 265,460 for roller or ball bearings.-

Referring to the drawings Figure 1. is a sectionalelevation of one form of bearing constructed in accordance with this invention. 4

r Fig. 2. is an elevation partly in section of the helix.

Fig. 3. is a sectional elevation of another Fig. 4. is a secti form of bearing, and

onal elevation Ora further a Fig. 5. is a sectlonal elevation showing an arran ement of doublebearing.

In t e construction shown in the rollers 2 01' balls and the hehx'are sup- Figs. 1 and 2 ported in a housing as shown and the helix is the helix parallel. In this arrangement the rollers2 or balls contact with the inner members 14 and a clearance 16 is provided between the outer surface of the helix and the inner surface of the housing 6. The clearance 16 extends for the whole length of the helix and permits expansion thereof.

The construction shown in Fig. 3 illustrates another method of securing the helix and rollers or balls and it comprises a housing formed from two annular rings 18 of angle section, the rollers '2 being held between the two rings 18 while the helix 1' is supported in the annular'recess 19,formed by the angle pieces. It will be understood that the rings 18 will be contained in a suitable outer housing which is not shown in the drawing, and it will be observed that an annular clearance 19 is provided exterior to the helix 1 which clearance extends for the whole length of the helix and permits its expansion. I

In Figs. 4 and 5 two other forms of the invention are illustrated, in the former as shown by Fig. 4 the helix 1 is disposed within the ring of rollers2 or balls. In this construction the helix 1 is supported in a suitable two art housing 20 and a clearance 21 is provided between the helix 1 and the housing 20. This clearance 21 extends for the whole length of the helix and allows of its contraction. For convenience in construction and in order to have a greater arrange a helix such as 1 exterior to the ring of balls or rollers 2.

Referring to Fig. 5 in this case the helix 1 is supported on two rings of rollers 2 carried by housings 22 and the shaft 5 is provided with a collar or flan e 23 which is supported by the helix L l he housings 22 are carried in an outer housing 23" and a clearance 24 18 provided between the extenor of the helix 1 and the outer housing 23. The clearance 24 extends for the whole length of the helix 1 and permits of its expansion. The shaft 5 does not bear upon the housing 22 but passes loosely therethrough. The shaft 5 is supported by its flange or collar 23 resting upon the helix 1 which rotates with it. The helix is supported on the rollers 2 which in turn are supported by the housings 22 which do not rotate.

Instead of making the coiled strips or helices with parallel or sloping sides they may be formed to inter-engage by making the sides concave or convex.

Any known means may be provided for adjusting the tension or diameter of the helix in any of the constructions hereinbefore described.

'hat we claim then is 1. In a bearing, rotatable anti-friction members disposed between a pair of races, one of which is a ring of solid construction and the other of which is formed as a close helix having an interior surface and an exterior surface a portion of one of which forms a race for the anti-friction members, means for supporting said helix said means contacting that surface of the helix a portion of which constitutes a race, and a clearance between the whole of the opposite surface of the helix and said supporting means.

2. In a bearing, rotatable anti-friction members disposed between a pair of races, one of which is a ring of solid construction and the other of which is formed as a close helix comprising a plurality of coils said helix having an interior surface and an exterior surface a portion of one of which forms a race for the anti-friction members, means for supporting said helix said means contacting that surface of the helix a portion of which constitutes a race, and a clearance between the whole of the opposite surface of the helix and said supporting means.

3. In a bearing, rotatable anti-friction members disposed between a pair of races, one of which is a ring of solid construction and the other of which is formed as a close helix comprising a plurality of coils having inter-engaging sides, said helix having an interior surface and an exterior surface a portion of one of which forms a race for the anti-friction members, means for supporting said helix said means contacting that surface of the helix a portion of which constitutes a race, and a clearance between the whole of the opposite surface of the helix and said supporting means.

4. In a bearing, rotatable anti-friction members disposed between a pair of races, one of which is a ring of solid construction and the other of which is formed as a close helix comprising a plurality of coils some of which have inclined sides, the middle coils being wider in cross section at. the outer periphery and the end coils being wider in cross section at theinner periphery, said helix having an interior surface and an exterior surface a portion of one of which forms a race for the anti-friction members, means for supporting said helix said means contacting that surface of the helix a portion of which constitutes a race, and a clearance between the whole of the opposite surface of the helix and said supporting means.

In testimony whereof we affix our signatures in presence of witnesses.
